Reading the refrigerator display

On a refrigerator the code shows on the control panel or dispenser display. Some models flash a letter or alternate two characters; hold the code in view and note both. LG codes are short letter pairs; a capital O differs from a zero.

LG appliances show short alphabetic codes (OE, IE, UE on washers, Er plus letters on refrigerators) and, on ThinQ models, a Smart Diagnosis option. LG also builds many Kenmore Elite units. The codes apply to model numbers such as LDF7774ST, LDT5678SS and DLEX3900B; check the label on your unit to confirm yours.

What causes Er dH

How to fix it

  1. Move food to a spare fridge.
  2. Unplug the refrigerator.
  3. Leave doors wide open one day in summer, three in winter, until all ice melts and water reaches the drain tray.
  4. Plug in and let it reach temperature.
  5. If it returns, the heater, fuse or board needs testing.
